Abstract (en)
[origin: US2002008904A1] The present invention relates to an optical arrangement for deflecting a light beam (1, 14), in particular in two substantially mutually perpendicular directions (2, 3), preferably for applying to confocal scanning microscopes, having two mirrors (8, 10) which can be rotated by means of a rotary drive (4, 5) in each case about mutually perpendicular axes-the x-axis (6) and y-axis (7)-one of the two mirrors (8, 10) being assigned a further mirror (9) in a prescribed angular position in a rotationally fixed fashion such that the mutually assigned mirrors (8, 9)-first and second mirrors-rotate jointly about the y-axis (7), and in so doing rotate the light beam (1, 14) about a pivot (11) which lies on the axis of rotation (6)-the x-axis-of the third mirror (10). In order to minimize and, in the ideal case, to eliminate the distortion errors produced by the arrangement, the optical arrangement is characterized in that the mirrors (8, 9, 10) are arranged in such a way that the optical axis of the light beam (12) running between the second and the third mirrors (9, 10) always lies substantially in a plane containing the x-axis (6) and perpendicular to the y-axis (7).
